AB  - Lindane belongs to the persistent organic pollutants (POPs) group, which can cause carcinogenic,
endocrine, and neurological problems in an organism. The widespread presence of lindane in the
environment demands efficient methods of its removal. In the present work, we investigated the
removal of lindane from an aqueous solution using a synthesized macroporous copolymer surface
modified with different functional groups through two-step post-functionalization. The modified
copolymer was characterized by Fourier transform infrared spectroscopy (FTIR-ATR), scanning
electron microscopy (SEM), and mercury intrusion porosimetry. For the kinetics of lindane sorption,
pseudo-first-order, pseudo-second-order, Elovich, Avrami, and fractional power models were used
via linear and non-linear regression analyses. The quality of the fitting of each model to experimental
data was assessed based on seven error functions: coefficient of determination (R2), Marquardt’s
percent standard deviation (MPSD), Chi-square statistic test (χ2), hybrid fractional error function
(HYBRID), the sum of the errors squared (SSE), sum of the absolute errors (EABS), and average
relative error (ARE). The investigation of error estimation methods showed that the pseudo-secondorder
model best fits the experimental kinetics data for both regression analyses. The mechanism of
lindane sorption was investigated by subjecting the data to the liquid film diffusion model,
intraparticle diffusion model, Bangham, and Boyd models. The results showed that intraparticle
diffusion was not the sole rate-controlling step; film-diffusion also affected the sorption process.

AB  - In the present study, synthesized macroporous copolymer was used for the sorption of lindane
from an aqueous solution. This organochlorine pesticide is classified, according to US EPA, as
mutagenic and teratogenic. Residues of lindane can persist in the environment, migrate long
distances, and cause widespread contamination. In this way, lindane residues can reach the
human body through the food chain. The usage of this pesticide is banned in most countries.
However, lindane remains a serious toxicological problem at industrial sites where lindane was
used coupled with improper wastewater disposal and has led to serious contamination. In
addition, some countries still allow the production and use of lindane, and despite localized
restrictions, lindane contamination remains a global problem. Taking into account these
reasons, its removal from the environment is of a great significance. The obtained macroporous
copolymer was syntesized via suspension copolymerization and was characterized by Fourier
transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The
parameters which affect sorption efficiency of the lindane were: pH, sorption time (tsor), ion
strength (ion), rpm, and dose of sorbent. These variables were optimized by the experimental
design which include Plackett-Burman Design (PBD) and Central Composite Design (CCD).
After screening step by the PBD, the optimum conditions were obtained by the CCD where the
values were investigated in two levels. The design of experiment showed that the ion strength
and dose of sorbent were the most significant parameters, while the other variables do not have
such an effect on sorption efficiency. Accordingly, the optimum conditions to reach the maximum
recovery were: pH 8, 180 min sorption time, 300 rpm, 2 w/v % ion strength and 8 g/l dose of
sorbent. The results showed that the studied copolymer could be an efficient sorbent for trace
lindane in water with recoveries above 80 %.
